Of course you will receive your credits when you win. WGT verifies all scores.
The only ones who don't receive credits are those who have been caught cheating or are in other violations of the Terms and Conditions. Specifically those who create another avatar to play in lower ranked tiers. It is a sad state of affairs when people feel they have to cheat others for a dollar on a free game, but it happens... and, sadly again, happens too frequently here at WGT.
Hence the verification of scores.
Congratulations on winning the event, tincupped!
